Improvement in lubricating compounds



UNITED STATES PATENT OFFICE E. FREEMAN PRENTISS, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVEMENT IN LUBRIOATING-COM POUNDS.

Specification forming part of Letters Patent No. 12,964, dated May 29, 1855.

-tion of the ingredients and mode of manulac' tnring the said wool-oil.

The natu're'of, my invention consists in the preparation and manufacture of an oil which answers the same purpose andis much cheaper than the. various kinds of oils which are'used in-the manufacture of woolen goods of all doscriptions in carding and weaving.

To prepare the wool-oil I take a quantity'of oil-soap, indifferent as to limep'rorided the quality be good, and dissolve the same in hot water-say about thirty pounds of oil-soap to thirty gallons of water, or a sufficient quantity of hot-water to entirely dissolve the oil-soap,

as the water will only dissolve a certain quan tity of the oil-soap. I then take an equal quantity-gallon for gallon-'-of olive, lard, rapeseed, or any other kind of oil which can be used on wool in the process of its manufactnre,'and mix with it the preparation aforesaid--to wit.,

the soap solution-which after such mixture, is

ready to be usedon the wool ,with an equally beneficial eflect as if pure oil only had been used. -The said wool-oil will not decompose by age; Neither can spontaneous combustion be produeed-from'its use on wool. It will not decomp0se,'because the oil of soap neutralizes the stearine matterin the oil. Hence there is nothing to decompose, and spontaneous com? bustion cannot be produced for the same reason.

WhatIclaim as my invention, and desire to secure by Letters Patent, is-

The manufacture or preparation of a compound which 1 denoininate wool-oil,-ot' the ingredients in the manner and-for the purpose set forth. E. FREEMAN PRENTISS.
